title: The association of overweight and obesity with blood pressure among Chinese children and adolescents.
abstract: OBJECTIVE
  To examine the association between obesity and high blood pressure (BP) in Chinese children and adolescents.
  
  
  METHODS
  Body mass index (BMI) and blood pressure measurements of 197 191 children aged 7-17 years were obtained from a Chinese national survey in 2010. Obesity and high BP were defined according to the reference values for Chinese children. Adjusted odds ratios (ORs) and 95% confidence intervals (CIs) of different BMI categories for high BP, as well as the population attributable risk percent (PAR%), were also calculated.
  
  
  RESULTS
  The prevalence of high BP was 16.1% for boys and 12.9% for girls in 2010. Overweight and obese children had a significantly higher prevalence of high BP than non-overweight children in both boys and girls in each age group. ORs (95% CI) for high BP were 4.1 (3.9, 4.4) in obese boys and 4.0 (3.7, 4.3) in obese girls. The overall PAR% for high BP due to overweight and obesity was 14.4%.
  
  
  CONCLUSIONS
  Overweight and obese children have a significantly higher risk of high BP than non-overweight children. Eliminating overweight and obesity could reduce 14.4% of high BP cases.
